BIG BROTHER 11 continued to gain momentum as last night's eviction broadcast posted its largest audience on any night and matched its highest adult 18-49 rating on any night, according to Nielsen preliminary live plus same day ratings for Thursday, Aug. 13.

Note: Due to local pre-season football, CBS had preemptions/delays in several markets. Ratings and time period rankings are tentative and subject to change.

For the night, CBS was first in households (5.1/09), viewers (7.71m), adults 25-54 (2.6/07) and adults 18-49 (2.0/06).
